很强大的最速下降法的C++算法程序，结果也比较精确-A very powerful method of steepest descent algorithm for the C++ program, the results more precise

The inverse of the gradient function. I ve provided versions that work on 1-d vectors, or 2-d or 3-d arrays. In the 1-d case I offer 5 different methods, from cumtrapz, and an integrated cubic spline, plus several finite difference methods. In higher dimensions, only a finite difference/linear algebra solution is provided, but it is fully vectorized and fully sparse in its approach. In 2-d and 3-d, if the gradients are inconsistent, then a least squares solution is generated

目前的商用有限元程序不但分析功能几乎覆盖了所有的工程领域，其程序使用也非常方便，只要有一定基础的工程师都可以在不长的时间内分析实际工程项目，这就是它能被迅速推广的主要原因之一。-The current commercial finite element analysis capabilities will not only cover almost all the engineering fields, and the procedure is also very easy to use, as long as there is some basis for engineers can be a long period of time without an analysis of actual projects, that is, it can be rapidly expanded one of the main.
